我是硒独立的新手。我已经下载了最新的java版本，单独使用NPM，XVFB，并尝试使用以下命令打开独立后创建会话：

sudo xvfb-run --server-args="-screen 0, 1366x768x24" selenium-standalone start -- -debug

请注意，我尝试使用Hub和Node尝试在本地客户端上使用C＃运行Selenium测试。

当我尝试创建Chrome会话时，我收到此错误（轮询将持续几秒钟）：

尝试运行此命令以安装最新的Stable Google Chrome：

sudo yum -y localinstall google-chrome-stable_current_x86_64.rpm

或

wget https://dl.google.com/linux/direct/google-chrome-stable_current_x86_64.rpm

我收到此错误：

 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

我无法在Linux AMI上安装库，但我最终做的是将其安装在Ubuntu实例上。这使用以下文档进行了非常简单的安装： https://www.npmjs.com/package/selenium-standalone

但是，我的Ubuntu linux也收到了二进制错误。问题是我的Linux机器上没有安装浏览器，我可以使用这里的说明： https://askubuntu.com/questions/510056/how-to-install-google-chrome

也适用于FireFox：

#install firefox browser
sudo apt-get install firefox
